TECHNICAL FIELD

The disclosure relates to an apparatus for glucose monitoring, in more particular, to an apparatus for non-invasive glucose monitoring.

BACKGROUND

Diabetes is a clinical syndrome caused by factors such as absolute or relative lack of insulin in the body, abnormal secretion time, or disorder or resistance of insulin effector, etc. If the diabetes is not suitably controlled, it may cause some acute complications such as hypoglycemia, ketoacidosis, nonketotic hyperosmolar coma, etc. The serious long-term complications include cardiovascular diseases, chronic renal failure, retinopathy, neuropathy and microvascular diseases, etc.

Constantly blood glucose monitoring is very important for diabetics. A primary objective of treating the diabetic is to maintain a normal glucose value, and if a patient carefully controls blood glucose daily, occurrence of the above complications may be effectively prevented.

Presently, the diabetic generally use blood glucose monitor to monitor the blood glucose. However, before the blood glucose monitor is used to measure a concentration of blood glucose, blood collection has to be first performed. Fingertip is an invasive (destructive) sampling method for blood collection, and a process thereof is complicated and may cause pain, which is also an important reason why the diabetic cannot periodically monitor the blood glucose.

Therefore, a method for non-invasive blood glucose monitoring becomes a development trend in blood glucose detection. The existing non-invasive glucose meters measure the blood glucose through a single method (for example, an acoustic method, an optical method or an electrical method), though the measurements are mainly performed in allusion to skin blood glucose of human body. However, the skin is composed of epidermis, dermis, subcutaneous tissues, and different tissues, blood vessels and water in the skin may produce scattering light and absorption light, which may influence signal measurement, and accordingly influence the measured blood glucose value.

FIG. 1B is a schematic diagram illustrating an optical rotatory distribution measuring device from FIG. 1A in accordance with the first exemplary embodiment.

With reference to FIG. 1A, an apparatus for non-invasive glucose monitoring 100 which comprises a light source 102, a first beam splitter 104, a set of photo detectors 106, and a processing unit 108. The apparatus for non-invasive blood glucose monitoring 100 may, for example, detect glucose of an aqueous humor 204 in an anterior chamber 202 of an eyeball 200.

The light source 102 generates at least one ray of light 110. The light source 102 is, for example, a light emitting diode (LED), a laser diode, or other light source. A wavelength of the light source 102 is, for example, which can be absorbed by glucose and namely, a wavelength that is capable of being absorbed by the glucose in the eyeball 200, such as an infrared light. The light 110 emitted from the light source 102 comprises a linear polarized light, a circular polarized light, an elliptical polarized light, or a partial polarized light. Moreover, the light source 102 may have a function for controlling an emitting frequency of the light 110, which avails the photo detector set 106 in determining the light to be measured according to the emitting frequency. In addition, the light source 102 may have a function for controlling an intensity of the light 110, which assures the light entering into the eyeball 200 is unable to cause any harm. Furthermore, the light source 102 may have a function for controlling a length of turn-on time of the light 110 and controlling a length of turn-off time of the light 110, or a combination thereof, which provides a glucose detection time on one hand but also ensures that the light energy entering into the eyeball 200 is unable to cause any harm on the other hand. Although, in the present exemplary embodiment, the single light 110 emitted from the single light source 102 is taken as an example for description, the disclosure is not limited thereto; and, in another exemplary embodiment, types of the light source 102 and types of the light 110 may be two or more.

The first beam splitter 104 with a focusing function which can lead the light 110 emitted from the light source 102 into an eyeball 200 and focus on the eyeball 200 through the first beam splitter 104. The first beam splitter 104 is, for example, focusing the light 110 onto the anterior chamber 202 of the eyeball 200, and the light 110 reflected from the eyeball 200 comprises the light reflected from the aqueous humor 204. The first beam splitter 104 is, for example, an optical film, a lens, a grating, a diffractive optic device or a combination of any the above elements.

The set of photo detectors 106 measures an optical rotatory distribution information and an absorption energy information of the light 110 reflected from the eyeball 200 and then transmitted through the first beam splitter 104 to the set of photo detectors 106. In the present exemplary embodiment, the set of photo detectors 106 comprises an optical rotatory distribution measuring device 112 and an energy measuring device 114. Wherein, the optical rotatory distribution measuring device 112 is used for measuring the optical rotatory distribution information of the light 110 reflected from the eyeball 200 and then reflected by the first beam splitter 104, and the energy measuring device 114 is used for measuring the absorption energy information of the light 110 reflected from the eyeball 200 and then passed through the first beam splitter 104.

In another exemplary embodiment, the optical rotatory distribution measuring device 112 and the energy measuring device 114 may be exchanged. Namely, the optical rotatory distribution measuring device 112 is used to measure the optical rotatory distribution information of the light 110 reflected from the eyeball 200 and then passed through the first beam splitter 104, and the energy measuring device 114 is used to measure the absorption energy information of the light 110 reflected from the eyeball 200 and then reflected by the first beam splitter 104.

With reference to FIG. 1B, the optical rotatory distribution measuring device 112 comprises a polarizer 112 a and a light sensing element 112 b, wherein the light is firstly passed through the polarizer 112 a, and then transmitted to the light sensing element 112 b. The optical rotatory distribution measuring device 112 is, for example, an active optical rotatory distribution measuring device or a passive optical rotatory distribution measuring device, wherein a measurement angle of the active optical rotatory distribution measuring device may be changed whereas a measurement angle of the passive optical rotatory distribution measuring device is fixed. The active optical rotatory distribution measuring device is, for example, an analyzer which may directly calculate the optical rotatory distribution information. The passive optical rotatory distribution measuring device is to measure the energy of the light 110 that passed through a polarizer 112 a using the light sensing element 112 b to calculate the angular information of the optical rotatory distribution information. The energy measuring device 114 is, for example, a light sensing element such as a charge coupled device (CCD), a complementary metal oxide semiconductor sensors or a light emitting diode.

Moreover, with reference to FIGS. 1A and 1B, the apparatus for non-invasive glucose monitoring 100 may further selectively comprise at least one of a light barrier 113 and a light barrier 115. The light barrier 113 has an opening 113 a, and the opening 113 a, through assembly, may enable the light 110 to pass through the light barrier 113, and then transmit to the light sensing element 112 b. The light barrier 113 is, for example, disposed between the polarizer 112 a and the light sensing element 112 b, but the disclosure is not limited thereto. In other exemplary embodiments, the light barrier 113 may further enable the light 110 to pass through the polarizer 112 a and then through the opening 113 a of the light barrier 113. In addition, the light barrier 115 has an opening 115 a, and the opening 115 a, through assembly, may enable the light 110 to pass through the light barrier 115, and then transmit to the energy measuring device (e.g., light sensing element). The light barriers 113, 115 respectively are, for example, a metal photomask or a silica glass photomask. The light barriers 113, 115 respectively may prevent stray light from entering into the optical rotatory distribution measuring device 112 and the energy measuring device 114, and thus may reduce interference from the stray light, so as to enhance the signal to noise ratio (S/N ratio). It is noted that each of the following exemplary embodiments, through the light barrier, may reduce the influence of stray light on the measurement results of the optical rotatory distribution measuring device and of the energy measuring device; however, further elaboration on the light barrier in the other exemplary embodiments are omitted in order to simplify the description.

Referring to FIG. 1A again, the processing unit 108 is, for example, coupled to the optical rotatory distribution measuring device 112 and the energy measuring device 114 of the set of photo detectors 106, and receives and processes the optical rotatory distribution information and the absorption energy information to obtain an optical rotatory distribution difference and an absorption energy difference between the light 110 emitted from the light source 102 and the light 110 transmitted to the set of photo detectors 106, and to obtain biological molecule information, which at least comprises a glucose, by analyzing the optical rotatory distribution difference and the absorption energy difference. The processing unit obtains the glucose information through analyzing the biological molecule information. The biological molecule is, for example, cholesterol, uric acid, water, lactic acid, urea, ascorbic acid, or a combination thereof. Moreover, the biological molecule may comprise one kind of interference molecules therein, and the kind of interference molecule is, for example, one kind of molecule different from the measurement target (e.g., glucose), such as cholesterol, uric acid, water, lactic acid, urea, or ascorbic acid. As ascorbic acid and lactic acid may generate interference onto the optical rotatory distribution information, whereas water may generate interference to the absorption energy information. During the process of obtaining the glucose information through the processing unit 108, the processing unit 108 may remove interference caused by the interference molecules. The processing unit 108 may also control a light source variation, an opto-element offset or a combination thereof, and statistically analyze the optical rotatory distribution information and the absorption energy information, so as to obtain the glucose information. The spatial variation of the light source comprises a light emitting frequency variation, a light energy intensity variation, a length variation of turn-on time of the light, a length variation of turn-off time of the light, or a combination thereof. Since the glucose concentration in the eyeball 200 (e.g., aqueous humor within eyeball) has a corresponding relationship with a blood glucose concentration, the blood glucose information (e.g., blood glucose value) can be determined according to the relationship. The processing unit 108 is, for example, an analog digital circuit integration module, wherein the analog digital circuit integration module comprises a microprocessor, an amplifier and an analog digital converter (ADC). The analog digital circuit integration module may further comprise a wireless transmission device.

In the present exemplary embodiment, the processing unit 108 is, for example, coupled to the light source 102 to control an optical characteristic of the light 110 emitted from the light source 102.

The apparatus for non-invasive blood glucose monitoring 100 may selectively comprise a light information analysis unit 116 for detecting a light information of the light 110 from the first beam splitter 104 before the light 110 is leaded into the eyeball 200, and selectively transmit the light information of the light 110 to the processing unit 108 or an alarm 118 to perform a feedback control with the optical characteristic of the light 110. The light information analysis unit 116 comprises at least one of an optical power meter and an optical sensor, the light information detected by the optical power meter is energy information whereas the light information detected by the optical sensor is at least one of energy information or position information. The optical characteristic of the light 110 is, for example, energy emittance and/or light position.

When the emitting energy of the light 110 emitted from the light source 102 is excessively high, where the light 110 may cause harm to the eyeball 200. Therefore, when the processing unit 108 receives the energy information indicating excessive emitting energy of the light 110, the processing unit 108 will reduce the emitting energy of the light 110 emitted from the light source 102. On the other hand, when the alarm 118 receives the energy information indicating excessive emitting energy of the light 110, the alarm 118 sends a light or a sound warning signal to notify the user that the emitting energy of the light 110 emitted from the light source 102 is excessively high, and the emitting energy of the light 110 is to be adjusted. Therefore, usage of the light information analysis unit 116 may prevent a condition of harming the eyeball 200 due to excessive emitting energy of the light 110.

Moreover, when the light position of the light 110 emitted from light source 102 is shifted, the accuracy of a blood glucose measurement is lowered. Therefore, when the processing unit 108 receives the position information indicating the light position of the light 110 is shifted, the processing unit 108 adjusts the light position of the light 110 emitted from the light source 102. On the other hand, when the alarm 118 receives the position information indicating the light position of the light 110 is shifted, the alarm 118 sends the light or the sound warning signal to notify the user that the light position of the light 110 emitted from the light source 102 is shifted, and the light position of the light 110 is to be adjusted. Therefore, usage of the light information analysis unit 116 may prevent the light position of the light 110 from shifting, thus enhancing the accuracy of the blood glucose measurement.

In the present exemplary embodiment, the energy information detected by the light information analysis unit 116 is simultaneously transmitted to the processing unit 108 and the alarm 118; nevertheless, the feedback control may be implemented as long as the energy information is transmitted to one of the processing unit 108 and the alarm 118. The light information analysis unit 116 is, for example, respectively coupled to the processing unit 108 and the alarm 118, but a coupling manner of the light information analysis unit 116, the processing unit 108 and the alarm 118 is not limited thereto.

In another exemplary embodiment, the light source 102 is, for example, coupled to a light source control unit (not shown), and now the light information analysis unit 116 transmits the energy information of the light 110 to the light source control unit, so as to perform the feedback control for the light source 102.

In addition, before the light 110 is leaded into the eyeball 200, the detection of the light 110 reflected by the first beam splitter 104 using the light information analysis unit 116 is taken as an example to describe the present exemplary embodiment.

Furthermore, the apparatus for non-invasive glucose monitoring 100 may further selectively comprise an eye-alignment position device 120 for aligning the sight of an eye 122 with the eye-alignment position device 120, so as to determine a measuring position of the eyeball 200. The eye-alignment position device 120 is, for example, a light spot, a marker, or a relief pattern.

On the other hand, the apparatus for non-invasive glucose monitoring 100 may further selectively comprise a joint element 124. A light outlet of the joint element 124, located at the apparatus for non-invasive glucose monitoring, is used for relying on an outer corner an eye. Moreover, the apparatus for non-invasive glucose monitoring 100 may further selectively comprise a protective cover 126 disposed on a surface of the joint element 124 that is used for relying on the outer corner of eye. The protective cover 126 is, for example, a disposable protective cover.

According to the first exemplary embodiment, the apparatus for non-invasive blood glucose monitoring 100 may simultaneously analyze the optical rotatory distribution difference and the absorption energy difference between the light 110 emitted from the light source 102 and the light 110 transmitted to the set of photo detectors 106, thus obtaining the glucose information (e.g., glucose value), and since the glucose concentration in the eyeball 200 (e.g., aqueous humor within eyeball) has a corresponding relationship with a blood glucose concentration, the blood glucose information (e.g., blood glucose value) with high accuracy is read through the corresponding relationship.

Moreover, the apparatus for non-invasive blood glucose monitoring 100 may be miniaturized in applications, for example, used in form of a headband or used in collaboration with glasses, so as to improve utilization convenience. In addition, the utilization environment of the apparatus for non-invasive blood glucose monitoring 100 has no special restriction, and thus may be utilized indoors or outdoors.

Referring to FIG. 1A and FIG. 2, a difference between the apparatus for non-invasive blood glucose monitoring 300 of the second exemplary embodiment and the apparatus for non-invasive blood glucose monitoring 100 of the first exemplary embodiment is that an optical rotatory distribution measuring device 312 and an energy measuring device 314 in a set of photo detectors 306 of the second exemplary embodiment are located at a same side of the first beam splitter 104, and the optical rotatory distribution measuring device 112 and the energy measuring device 114 in the set of photo detectors 106 of the first exemplary embodiment are located at two sides of the first beam splitter 104, respectively. The optical rotatory distribution measuring device 312 and the energy measuring device 314 are, for example, coupled to the processing unit 108, respectively, but the disclosure is not limited thereto. Compositions, coupling relations and functions of the other components of the apparatus for non-invasive blood glucose monitoring 300 of the second exemplary embodiment are similar to that of the apparatus for non-invasive blood glucose monitoring 100 of the first exemplary embodiment, so that detailed descriptions thereof are not repeated.

In the present exemplary embodiment, the set of photo detectors 306 is, for example, used to measure the light 110 reflected from the eyeball 200 and then reflected by the first beam splitter 104. The light 110 to be measured is first transmitted to the optical rotatory distribution measuring device 312 for measuring the optical rotatory distribution information, and then transmitted to the energy measuring device 314 for measuring the absorption energy information. In another exemplary embodiment, the set of photo detectors 306 may also be used to measure the light 110 reflected from the eyeball 200 and then passed through the first beam splitter 104.

In another exemplary embodiment, the apparatus for non-invasive blood glucose monitoring 300 further comprises another set of the optical rotatory distribution measuring device 312 and the energy measuring device 314, so that the apparatus for non-invasive blood glucose monitoring 300 has two sets of the optical rotatory distribution measuring device 312 and the energy measuring device 314 for respectively measuring the optical rotatory distribution information and the absorption energy information of the light 110 reflected from the eyeball 200 and then passed through the first beam splitter 104, and for measuring the optical rotatory distribution information and the absorption energy information of the light 110 reflected from the eyeball 200 and then reflected by the first beam splitter 104.

Similarly, the apparatus for non-invasive blood glucose monitoring 300 of the second exemplary embodiment may simultaneously analyze the optical rotatory distribution difference and the absorption energy difference between the light 110 emitted from the light source 102 and the light 110 transmitted to the set of photo detectors 306 to obtain the glucose information (e.g., glucose value), and since the concentration of glucose in the eyeball 200 (e.g., aqueous humor within eyeball) has a relationship with a blood glucose concentration, the blood glucose information (e.g., blood glucose value) with a high accuracy is read through the corresponding relationship. Moreover, the apparatus for non-invasive blood glucose monitoring 300 may be miniaturized, so that it is convenient in utilization, and may be utilized indoors or outdoors.

FIG. 3 is a schematic diagram illustrating an apparatus for non-invasive glucose monitoring in accordance with a third exemplary embodiment.

Referring to FIG. 1A and FIG. 3, a difference between an apparatus for non-invasive blood glucose monitoring 400 of the third exemplary embodiment and the apparatus for non-invasive blood glucose monitoring 100 of the first exemplary embodiment is that the apparatus for non-invasive blood glucose monitoring 400 of the third exemplary embodiment further comprises a second beam splitter 404, and a set of photo detectors 406 comprises a first photo detector 408 and a second photo detector 410. Compositions, coupling relations and functions of the other components of the apparatus for non-invasive blood glucose monitoring 400 of the third exemplary embodiment are similar to that of the apparatus for non-invasive blood glucose monitoring 100 of the first exemplary embodiment, so that detailed descriptions thereof are not repeated.

The second beam splitter 404 transmits the light 110 reflected from the eyeball 200 and then transmitted through the first beam splitter 104 to the set of photo detectors 406. The second beam splitter 404 is, for example, an optical film, an optical lens, an optical grating, a diffractive optical element or a combination of any the above elements.

The first photo detector 408 is used to measure the light 110 reflected by the second beam splitter 404, and the second photo detector 410 is used to measure the light 110 passed through the second beam splitter 404. The first photo detector 408 comprises an optical rotatory distribution measuring device 412 and an energy measuring device 414, and the second photo detector 410 comprises an optical rotatory distribution measuring device 416 and an energy measuring device 418. The light 110 to be measured is, for example, first transmitted to the optical rotatory distribution measuring device 412 (or 416) for measuring the optical rotatory distribution information, and then transmitted to the energy measuring device 414 (418) for measuring the absorption energy. Composition of the optical rotatory distribution measuring device 412 (or 416) is similar to that of the optical rotatory distribution measuring device 112, and composition of the energy measuring device 414 (or 418) is similar to the energy measuring device 114, so that descriptions thereof are not repeated. When the first photo detector 408 and the second photo detector 410 in the apparatus for non-invasive blood glucose monitoring 400 may simultaneously measure the optical rotatory distribution information and the absorption energy, by cross-comparing the obtained two sets of the optical rotatory distribution information and the absorption energy, the optical rotatory distribution difference and the absorption energy difference between the light 110 emitted from the light source 102 and the light 110 transmitted to the set of photo detectors 406 may be analyzed to obtain the glucose information (e.g., glucose value), and since the glucose concentration in the eyeball 200 (e.g., aqueous humor within eyeball) has a relationship with the concentration of blood glucose, the blood glucose information (e.g., blood glucose value) with high accuracy is read through the corresponding relationship. The optical rotatory distribution measuring devices 412, 416 and the energy measuring devices 414, 418 are, for example, respectively coupled to the processing unit 108, but the disclosure is not limited thereto.

It is noted that when the optical rotatory distribution measuring devices 412, 416 are all passive optical rotatory distribution measuring devices and respectively comprise a polarizer, the polarizers in the optical rotatory distribution measuring devices 412, 416 are, for example, one of a horizontal polarizer and a vertical polarizer, or two sets of polarizers with known optical rotatory distribution angles. If the two sets of the polarizers with known optical rotatory distribution angles are used, one of the measuring methods thereof is to compare energy differences of the two sets of the polarizers, and according to the energy differences, the optical rotatory distribution difference within a certain range of glucose concentration is obtained, so as to improve the detection accuracy. Another method is to use the two sets of polarizers with known optical rotatory distribution angles to determine offset components according to the absorption energy differences, so as to calculate the optical rotatory distribution information.

In another exemplary embodiment, one of the first photo detector 408 and the second photo detector 410 is, for example, a single optical rotatory distribution measuring device, and another one of the first photo detector 408 and the second photo detector 410 is, for example, a single energy measuring device.

Although, in the aforementioned exemplary embodiment, the light 110 reflected by the second beam splitter 404 and/or the light 110 passed through the second beam splitter 404 is one ray of light. However, the light 110 reflected by the second beam splitter 404 and/or the light 110 passed through the second beam splitter 404 may be divided into two or more rays of light by the second beam splitter 404, and then measured by the aforementioned first photo detector 408 and the second photo detector 410.

According to the third exemplary embodiment, the apparatus for non-invasive blood glucose monitoring 400 may simultaneously analyze the optical rotatory distribution difference and the absorption energy difference between the light 110 emitted from the light source 102 and the light 110 transmitted to the set of photo detectors 406 to obtain the glucose information (e.g., glucose value), and since the concentration of glucose in the eyeball 200 (e.g., aqueous humor within eyeball) has a relationship with the concentration of blood glucose, the blood glucose information (e.g., blood glucose value) with a high accuracy is read through the corresponding relationship. Moreover, the apparatus for non-invasive blood glucose monitoring 400 may be miniaturized, so that it is convenient in utilization, and thus may be utilized indoors or outdoors.

FIG. 4 is a schematic diagram illustrating an apparatus for non-invasive glucose monitoring in accordance with a fourth exemplary embodiment.

Referring to FIG. 3 and FIG. 4, a difference between an apparatus for non-invasive blood glucose monitoring 500 of the fourth exemplary embodiment and the apparatus for non-invasive blood glucose monitoring 400 of the third exemplary embodiment is that, in the apparatus for non-invasive blood glucose monitoring 500 of the fourth exemplary embodiment, a set of photo detectors 506 comprises a first photo detector 508 and a second photo detector 510, and the first photo detector 508 and the second photo detector 510 are located at a same side of the second beam splitter 404. In the present exemplary embodiment, the first photo detector 508 and the second photo detector 510 are, for example, located at the side of the second beam splitter 404 where the light 110 passes there through, and are respectively used to measure two rays of light 110 a, 110 b generated by the light 110 after passed through the second beam splitter 404. One of the first photo detector 508 and the second photo detector 510 is, for example, an optical rotatory distribution measuring device for measuring the optical rotatory distribution information, and another one of the first photo detector 508 and the second photo detector 510 is, for example, an energy measuring device for measuring the absorption energy information. The first photo detector 508 and the second photo detector 510 are, for example, coupled to the processing unit 108, respectively, but the disclosure is not limited thereto. Compositions, coupling relations and functions of the other components of the apparatus for non-invasive blood glucose monitoring 500 of the fourth exemplary embodiment are similar to that of the apparatus for non-invasive blood glucose monitoring 400 of the third exemplary embodiment, so that detailed descriptions thereof are not repeated.

Moreover, the apparatus for non-invasive blood glucose monitoring 500 may be miniaturized, so that it is convenient in utilization, and thus may be utilized indoors or outdoors.

FIG. 5 is a flow chat diagram illustrating a method for a non-invasive blood glucose monitoring in accordance with a fifth exemplary embodiment.

With reference to FIG. 5, firstly, step S90 may be selected performed for aiming the eyeball onto the eye-alignment position device to align the sight of the eye with the eye-alignment position device for performing alignment, wherein the alignment includes adjusting a relative angle and a position between the optical axis of the eye-alignment position device and the sight of the eye, so as to determine a measuring position of the eyeball. Next, in step S100, at least one ray of light is emitted through at least one light source. Then, step S102 may be selectively performed for controlling the optical characteristic of the light source, the opto-element offset or the combination thereof, and a change factor is produced thus facilitates in analyzing the blood glucose information more accurately. Wherein, the light source is used to control an emitting frequency of the light, an intensity of the light, a length of turn-on time of the light, a length of turn-off time of the light, or a combination thereof. The set of photo detectors may assure the light to be measured according to the emitting frequency of the light. Moreover, by controlling the intensity of the light through the light source, it is ensured that the light energy entering the eyeball is unable to cause any harm. In addition, by controlling the length of turn-on time of the light, the length of turn-off time of the light or the combination thereof through the light source, a time required for glucose detection is provided on one hand, and it is ensured that the light energy entering the eyeball is unable to cause any harm on the other hand. Then, step S104 may be selectively performed, by which before the light is leaded into the eyeball, the light information of the light from the first beam splitter is detected, so as to perform a feedback control with the optical characteristic of the light. The light information comprises at least one of the energy information and the position information. The optical characteristic is, for example, a position for emitting energy and/or light. Next, in step S106, the light emitted from the light source is leaded into the eyeball and focused on the eyeball through the first beam splitter with the focusing function. Then, one of step S108 and step S110 may be performed. Wherein, in step S108, the light reflected from the eyeball is transmitted to the set of photo detectors through the first beam splitter. In step S110, the light reflected from the eyeball is transmitted to the second beam splitter through the first beam splitter, and then the light is transmitted to the set of photo detectors through the second beam splitter. Furthermore, in step S112, the optical rotatory distribution information and the absorption energy information of the light transmitted to the set of photo detectors are measured by the set of photo detectors. Then, in step S114, the optical rotatory distribution difference and the absorption energy difference between the light emitted from the light source and the light transmitted to the set of photo detectors are obtained by processing the optical rotatory distribution information and the absorption energy information. Next, in step S116, the optical rotatory distribution difference and the absorption energy difference are analyzed to obtain the information of the biological molecule, wherein the biological molecule at least comprises the glucose, the glucose information is obtained through the biological molecule information, the glucose concentration in the eyeball (e.g., aqueous humor within eyeball) has a corresponding relationship with the concentration of blood glucose, the blood glucose information (e.g., blood glucose value) is read through the corresponding relationship. The biological molecule is, for example, cholesterol, uric acid, water, lactic acid, urea, ascorbic acid, or a combination thereof. Moreover, the biological molecule may comprise an interference molecule therein, and the interference molecule is, for example, different from the measurement target (e.g., glucose), such as cholesterol, uric acid, water, lactic acid, urea, or ascorbic acid. Wherein, ascorbic acid and lactic acid may generate interference to the optical rotatory distribution information whereas water may generate interference to the absorption energy information. Furthermore, in step S116, interference generated by the interference molecule may further be selectively removed. Variations of the method for non-invasive blood glucose monitoring and various used devices of the fifth exemplary embodiment have been described in detail in the first to the fourth exemplary embodiments, so that descriptions thereof are not repeated.

According to the above descriptions, in the method for non-invasive blood glucose monitoring of the fifth exemplary embodiment, since an optical eyeball detecting method is used to measure the glucose information (e.g., glucose value) of the measuring object, the glucose information (e.g., glucose concentration) of the measuring object may be continuously obtained in real time, and since the glucose concentration has a relationship with a blood glucose concentration, the blood glucose information (e.g., blood glucose value) may be read.
